First of all a very good post, ya pointed out that Huerta has faught no one spectacular, however could be a prospect in the division!
And yeah, I think its about time they gave him a step up in class...not anyone A level to be honest, I think a BJ Penn, Sean Sherk or even Joe Stevenson would defeat him wit ease...Huerta is very agressive and I noticed several times in the Crane fight that a better fighter would have punished him for what I consider bein a bit "sloppy"...
I think these fighters would be suitable for the "next" step:
Jorge Gurgel (tough lil SOB)
Melvin Guillard (Huerta has yet to fight a guy wit heavy hands)
Alvin Robinson (a descent fighter wit good ground skills)
Sam Stout (Has FOTN award written all over it)
